The Z2's earned their name because they feature twice the sound, twice the battery life, and twice the convenience of competing headphones. This updated version of the original Z2s comes with a new all-black design and Bluetooth 5.0. Packed with TREBLAB's most advanced Sound2.0™ technology with aptX and T-Quiet™ active noise-cancellation, these headphones deliver goosebump-inducing audio while drowning out unwanted background noise. It's like you're at a concert every time you turn up the volume.
